DJUSTABLE SWITCH-POXNT RAIL SECTION.

Application led April 22, 1922. Serial No. 556,043.

To all whom it 'may concern.'

Be it known that I, PHILIP CAMELI, a citizen of the United States of America, residing at llfilmington, in the county of New Castle and State of Delaware, have invented certain new and useful improvements in Adjustable Switcli-loint yRail Sections, of which the following is a specilication.

The present invention relates to improvements in adjustable switch point raill sections wherein the free ends of the switch points are forced into intimate engagement with a supporting tie to eliminate vibratory movement thereof in the passage of wheels of rolling stock over the point.

rllhe invention has particular reference to improvements over the different constructions of adjustable switch point rail sections shown and described in patent granted to me June 22nd, 1920, Number 1,344,259, and patent `granted March 29, 19.21, Number 1,372,935, these patents referring in detail 'to' tie bar No. l that is connected to the switch point adjacent the swinging ends thereof. A depending offset extension is carried by each end of the tie bar No. 1 and underlies the .base of the adjacent rail while a. vertically adjustable plate is mounted on the tie bar extension and is adjustable by screw bolts threaded through the tie bar extensions to cause the plate to engage the base of the rail with consequent lowering movement of the tie bar and switch point farried thereby to cause the switch point to lie in intimate contact with the supporting` tie.

The present invention eliminates the manuall operable screw bolt associated with tie bar ido. l 0f the rails for adjusting the switch points, and in lieu thereof provides autoA inatically operating means in the form of:

spring devices for holding the switch points properly positioned upon the tie, the switchy points being initially adjust-ed and thereafter. automatically kept adjusted to a proper position relative to the tie to cause a substantially frictional engagement between the switch points and tie.

1With the above general objects in view the invention consists of the novel lcombination andl arrangement of parts hereinafter more fully described in connection with accompanying drawings, and in which like reference characters designate corresponding parts throughout the several views.

ln the drawings:

Figure 1 is a top plan view of a portion of a railway track constructed in accord` ance with the present invention.` showing tie bar No. 1 connected to the switch points,

Figure 2 is a cross sectionalview of the track, showing the angle ends of tie bar No. l disposed beneath the track rails, the switch points carried by tie bar No. l and the `spring devices interposed between the tie bar extensions and the rails,

Figure 3 is a fragmentary side elevational view, partly in section of one end of tie bar No. 1 showing the depending angle offset extension carried by the end of the tie bar and the spring devices interposed between the tie bar extension and the rail en gaging plate.

Figure 4 is aperspective view of the rail engaging plate showing the counter-sunk openings therein for the heads of the guide bolts, and

Figure 5 is a fragmentary perspective view of one end of tie bar No, 1 with the openings therein for the passage of the guide bolts.

in the accompanying drawing, showing the preferred embodiment ofthe invention, the reference numeral l designates a cross tie of usual construction supporting rails 2 with which adjust-able switch points4 3 are associated. rlie bar No. l, designated by the reference numeral 4 is connected to the switch point 3 adjacent the swinging ends thereof. As shown in Figure -1 the tie bar carries a laterally extending socket 5 to which a switch arm (i is attached for throwing the switch points in the desired direction.

The tie bar No. l carries upon each end v.thereof lcpending offset extensions 7 provided with spaced openings 8 and is disposed beneath the rail 2 as shown in Figures 2 and A3, the same being materially spaced from the rails for purposes presently to ap pear. The points 3 are secured to tie bar No. l by the angle braces Stadjacent the offset end extensions and upon shifting movement of the tie bar are selectively positioned into engagement with a rail as shown in Fig- .urev2.

In the absence of devices for frictionally holding the switch points on the tie'No. 1, the samewill vibrate during passage of rolling stock thereover, resulting in damage thereto 1 and rendering the points inoperative. The present invention residing' in the provision of means automatically operable for maintaining frictional engagement between the switch points 3 and the tie 1, includes a plate 10 having spaced bolt receiving openings 11 registering withvthe bolt receiving openings 8 in the tie bar extension with the upper ends of the openings 11 -counter-sunk as at 12, and being of polygonal formation for the reception of a sirnilarly formed bolt head and preventing rotary movement of the bolt when positioned therein. As shown in Figure 3, the bolt 13 provided with a polygonahhead 14 and a threaded lower end 15 is positioned in the plate opening 11 with the head 14 received in the counter-sunk portion 12 of the opening 11, the lower threaded end lof the bolt freely passing through the opening 8 in the tie bar extension. rlhe railengaging plate 10 is positioned4 above the tie bar extension 7 and spaced therefrom, the bolt 13 depending from the plate l0 and freely passing through the openings 8 in the tie bar extension, nuts 16 being threaded upon the lower ends of the bolt beneath the tie bar eX- tension while cotter pins 17 are selectively positioned in transverse openings 18 formed in the threaded end of the bolt to prevent accidental displacement ofthe nut 16. A coil spring 19 surrounds each bolt 13 and engages at its opposite ends the rail engaging plate 10' and the tie bar extension 7, normally holding the partsI separated.v

In the setting and operation of the device, the nuts 16 and cotter pins 17 being removed from the screw bolts 13, the springs 19 will cause a separating movement of the rail engaging plates 1() and the tie bar extensions 7,

the plate 1() being moved by the springs into engagement with the rail, while the tie bar and extension 7 are lowered relative to the rail, this latter movement being limited by the switch points 3 secured to the tie bar intermediate the ends thereof as shown in Figure 2 by engagement with the tie 1. In adjusting the device and regulating the 'frictional engagement between the switch points and the'tie, the nuts 16 are threaded onto the lower ends of the bolts 13 for engagement withthe lower face of the tie bar eX- tension 7'compressing the springs 19 and regulating the extent of frictional engagement between the switch points and the tie,

and when so positioned, the cotters 17 are' inserted in the desired opening 18 of the bolt to'prevent the displacement of the nut 16 from the bolt. automatic in operation, after having been initially set', the springs 19 forcing the plate 10 upwardly into engagement with base of the rail 2 will cause a lowering movement of tie bar No. 1 by the springs 19 engaging the tie bar extensions 7, thereby frictionally holding .the switch points into engagement The device is entirelyv with the supporting tie to prevent 'rattlingor vibrating movement thereof during the passage of rollingstoclr thereover.

Having thus described the invention, what I claim as new is 1. In combination, a pair of switch point rail sections, and a tie bar connecting the same, the tie bar being resiliently' mounted switch point rail section associated there with, a tie bar 'carried by the switch point rail section and extending beneath the railway rail, and resilient devices interposed. between the rail-way rail and tie bar for causing a downward movement of the switch point rail section. f

Ll. In combination, a rail-way rail, a switch point rail section associated therewith, a tie bar carried by the switch point irail section. a plate carried by' the tie bar and arranged between the tie bar and railway rail and cushion devices interposed be'- tween the plate and tie bar whereby the switch point rail section is lowered onto the supporting tie.

In combination, a pair of switch point rail sections, va tie bar supporting the same, rail engaging'members associated with the tie bar and cushion springs interposed loetween the tie bar and rail engaging members to cause the switch point frictionally to engage the supporting tie.v

6. In combination, a pair of switch point rail sections, a tie bar connectinglthe same, a rail engaging member associatedv with each end of the tie bar, a bolt carried by the rail engaging member freely extending through the adjacent end of the tie bar and a coil spring surrounding the bolt between the rail engaging member and tie bar for frictionally holding the switch point inengagement with a supportin tie.

7. In com ination, a pair of switch point rail sections, a tie bar connecting the same, a rail engaging plate associated with each end of the tie bar, screw bolts carried by the rail engaging plates freely extending through the tie bar coil springs surrounding the bolts 'between the vrail engaging plates and the tie bar and a nut tln'oaded on each bolt into engagement with the tic bar regulating the extent of frictional engagement between the switch points and the supporting tie.

ln testimony whereof l affix my signature.
